PROFESSOR C. G. KNOTT ON MAGNETIZATION 
TasLe A, ; 
Containing the reduced results immediately deducible from the individual observa- 
tions of the experiments described above, and arranged in order of date, H 
being the magnetic force in the heart of the anchor-ring coil, t the temperature 
of the nickel coil at the instant, as determined by the measured resistance of the 
wire L, and dL being the change of resistance due to the magnetization.
